"Composition for the dyeing of keratin fibers and their use, the process of dyeing the keratin fibers, multi-compartment devices"

Field of the Invention

The present invention relates to a dye composition.

oxidation of keratin fibers.

Background of the Invention

Keratin fibers and in particular human hair are usually dyed with dye compositions containing oxidation dyes, in particular oxidation dye precursors and color modifiers.

Oxidation dye precursors, commonly referred to as oxidation bases, are initially colorless or faintly colored compounds which, in combination with oxidizing products, may give rise to a process of oxidative condensation to colored or coloring compounds. These are generally compounds such as ortho- or para-phenylenediamines, ortho- or para-aminophenols and heterocyclic bases.

It is also known that it is possible to vary the hues obtained with these oxidation bases by associating them with couplers or color modifiers, which are chosen in particular from meta-diaminobenzenes, meta-aminophenols, metadiphenols and certain heterocyclic compounds such as as indolic compounds.

The variety of molecules used in oxidation bases and couplers allows a rich color palette to be obtained.

The so-called "permanent" coloration obtained from these oxidation dyes, also called oxidation coloration, must still satisfy a number of requirements. Thus, it must be free from toxicological drawbacks, must provide shade at the desired power and have good resistance to external aggressions such as light, weather, washing, permanent undulation, perspiration and friction.

The dyes should also be able to cover white hair, and should be as little selective as possible, that is to say, to obtain the smallest possible color differences along the same keratin fiber, which generally comprises differently sensitized areas (or damaged) from tip to root.

Several attempts have been made in the field of hair dyeing to improve dyeing properties by, for example, adjuvants. However, the choice of these adjuvants is delicate because they must improve the tincture properties without impairing the other properties of these compositions. In particular, such adjuvants should not impair the whitening properties of the keratin fibers and the color application properties. The purpose of the present invention is to obtain novel compositions.

for the oxidation dye of keratin fibers that do not have the drawbacks of the prior art. More particularly, the purpose of the present invention is to obtain keratin fiber oxidation staining compositions, which have improved dyeing properties, and which are easy to mix and apply. By improved dyeing properties is meant in particular an improvement in the power / intensity and / or homogeneity of the dye.

Description of the Invention

Thus, this purpose is achieved by the present invention which has as object a composition for the oxidation dye of keratin fibers, and in particular of human keratin fibers such as hair, comprising:

(A) at least 25% fatty bodies, (B) one or more oxidation bases chosen from diaminopyrazones and their acid addition salts,

(C) one or more additional dye precursors other than the oxidation base as defined in (B),

(D) one or more oxidizing agents, and

eventually

(E) one or more alkaline agents.

The composition according to the present invention is distinguished by its improved dyeing properties. In particular, the composition of the present invention leads to dyes that exhibit good potency and / or color intensity to the fiber length between the tip and root of the hair (also called dye selectivity) and / or good chromaticity. The composition of the present invention is readily applied to the keratin fibers without draining. This composition further allows less degradation of keratin fibers during the coloration process.

Finally, the stains obtained with compositions of the present invention are tougher, and resist the various external aggressions to which keratin fibers are exposed.

The present invention also relates to a process for dyeing keratin fibers using the composition according to the present invention.

Λ

At the time of use, 10 g of A3 or A4 Composition is

mixed with 4 g of Composition B 'and 15 g of Composition C.

Each mixture is then applied to moderately sensitized (SA21) and strongly sensitized (SA42) locks, at a rate of 14.5 g of the mixture for 1 g of hair. After 30 minutes of resting at room temperature, the hair is rinsed, washed with a regular shampoo and dried.

Colorimetric measurements are performed with a

Datacolor SF600X Spectraflash Spectrocolorimeter (D65 illuminant, angle

10 °, specular components included).

Selectivity

Staining selectivity was also evaluated by the L * a * b * system. Color selectivity is the color variation between differently sensitized hair. Selectivity is representative of the uniformity of coloring across a strand of hair, as hair is generally not sensitized equally between root and tip. Selectivity is measured by:

ΔΕ, which is the color variation between different hair types, is

obtained from the formula: __

Δ E = J (L * - L0 *) 2 + (a * - a0 * f + (b * - b0 T

Where L * represents the intensity a * and b *, the chromaticity of the

sensitized colored hair (SA42) and L0 * represents the intensity and a0 * and b0 * the chromaticity of natural colored hair. The smaller the value of ΔΕ, the lower the selectivity and the more uniform the coloration along

of the hair. Hair Type L * A * B * ΔΕ A3 + B '+ C SA21 19.81 9.17 3.45 6.11 SA42 20.51 14.89 5.47 A4 + B' + C (invention) SA21 19.72 9.49 3.45 2.27 SA42 19.58 11.60 4.27

The mixture obtained with Composition A4 leads to a lower selectivity, therefore better, than the mixture obtained with Composition A3.
